Conventional motor oils may or may not have additives included after refining | com Motor oil is made from crude oil and is used to lubricate, clean, and cool engines |

Most consumer motor oils are graded by two numbers, with the first number indicating cold weather Winter or "W" performance |
A numerical code system created by the Society of Automotive Engineers SAE grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous thicker the oil is.
23Seal conditioners help reduce leaks• Extra additives are included to minimize compression loss, and to condition rubber seals and gaskets to prevent fluid leakage in older or high-mileage vehicles | Superior oil burn-off protection versus leading conventional oils• Advanced additives that help prevent engine wear• Castrol GTX High Mileage is the premium part synthetic motor oil specifically formulated for vehicles with over 75,000 miles |

by entering your model number | As your engine ages, gaskets become brittle, seals deteriorate and oil consumption increases |
Castrol GTX High Mileage is formulated with unique additive technology that combats this aging process and helps extend engine live by providing unsurpassed protection against sludge, wear and oil burn-off.
